well its a matter of opinion on what sounds better. Its just that a lot of people dont like the xpipe sound, it can be very raspy depending on the rest of your setup. xpipe sounds more like a race car to me,or like the european exotics. h pipe will be more like old school muscle. xpipe is more efficient it flows better. xpipe is also louder. simply, everyone likes the sound of the hpipe including me, not everybody likes the sound of the x pipe. but i think its pure sex when hit the gas.OK, just to clarify: X pipe makes better power but H pipe sounds better?
